A New Tool Could Make Fingerprint Analysis More Reliable

Contrary to what many would like to believe, fingerprint evidence isn't all that reliable. Partial prints and smudged prints can be difficult to read, and in the U.S. at least, fingerprint analysis is left to individual interpretation rather than a set of standards outlining what can be considered a match.

That could soon change, though. A statistical tool developed by a Department of Defense analyst is able to take two fingerprints and tell how probable it is that they came from the same person, according to Gizmodo. The software program, called FRStat, was used in a courtroom for the first time in February and is now available to any lab that wants to test it out.

Henry Swofford, of the U.S. Army Criminal Investigation Laboratory at the Department of Defense, spent four years working with statisticians to develop the software. It works by comparing images of the small features of fingerprint minutiae (ridges) against "similarly marked, known matches" in a database. The software is then able to calculate the likelihood that the prints were left by the same individual. A paper outlining the statistical method was published in the journal Forensic Science International.

"I want to strengthen the foundations of our science," Swofford told Gizmodo. "I also want to make sure the evidence is presented in a way that the guilty people are convicted, and the innocent are exonerated."

A 2011 study found a false positive rate of 0.1 percent among fingerprint readings, and there have been numerous high-profile cases of wrongful convictions over the years. In one example, Brandon Mayfield, a lawyer from Oregon, was arrested in connection with the 2004 Madrid train bombing after four experts agreed that his prints matched ones found on a bag at the scene. He was eventually released after that proved to be a mistake.

While FRStat isn't the first technology that attempts to make fingerprint analysis more accurate, it's the first one that has been developed for widespread, practical usage, according to Gizmodo.

Queen's 'Bohemian Rhapsody' Is Officially the Most Streamed Song of the 20th Century

Queen's "Bohemian Rhapsody" was a massive hit when it was released in 1975. After spending nine weeks at the top of the UK charts (it only broke the top 10 on the U.S. charts), it went on to become the third bestselling UK single of all time. Even as the way people listen to music has changed, the mock opera's popularity hasn't wavered. Now, "Bohemian Rhapsody" is officially the most streamed song recorded in the 20th century, Entertainment Weekly reports.

Queen's song has been streamed by listeners a staggering 1.5 billion times, putting it ahead of classic rock tracks like "Smells Like Teen Spirit" by Nirvana and "Sweet Child O' Mine" by Guns N' Roses. But when looking at overall streaming numbers, contemporary tracks still dominate. Combined, the original version of "Despacito" and the remix garnered 4.6 billion plays in just six months last year.

This latest milestone for "Bohemian Rhapsody" is even more satisfying when you know the song's backstory. The long play time and unconventional, operatic style made some music industry insiders—including the band's manager and Elton John—skeptical of its marketability. When the song debuted on the radio, listeners calling in to demand more quickly proved them wrong.

The track likely got a boost in popularity recently with help from the Freddie Mercury biopic that shares its name. Bohemian Rhapsody, starring Rami Malek, hit theaters in early November and is now officially the second-highest grossing musical biopic of all time, just behind 2015's Straight Outta Compton. But it's not the first time a hit movie has led to renewed interest in the song: the tune saw a similar spike in sales—and it reentered the charts and hit No. 2—when it played an integral part in the hit 1992 comedy Wayne's World.

The Pigzbe Wallet Teaches Kids How to Budget and Save Money

Fiscal responsibility isn’t the most exciting topic in the world, especially when you’re in elementary school. But, as Fast Company reports, Primo Toys is hoping to make the concept more child-friendly. The company’s new Pigzbe wallet works like a digital piggy bank to teach kids age 6 and older how to earn, budget, and save money by managing the cryptocurrency they receive from their parents.

Pigzbe connects to a smartphone app, which parents can use to set chores and tasks for their kids to complete, such as making their bed or washing the dishes. They can set a schedule for these chores (every Tuesday, for example) as well as monetary rewards in the form of Wollo, a “family-friendly” cryptocurrency developed by Primo Toys.

Tasks will be sent directly to the Pigzbe device, and once they have been completed, kids will receive their hard-earned Wollo tokens. The Pigzbe app helps kids visualize their earnings and how much they’ll need to save to get the items they want. "It’s a design that feels childlike, sure, but in a fun, self-aware way, almost like a Tamagotchi," Fast Company notes.

Although Wollo isn’t technically “real money,” the tokens can be used to purchase toys and other items from Pigzbe’s app. Parents can also order a specialized Visa card that will let them buy items using Wollo. Other family members can also send gifts and allowances to any Pigzbe user, no matter their geographic location.

The goal is to teach kids about financial responsibility at an early age, when they’re just beginning to form habits that will stick with them well into adulthood. “We believe that financially curious children become financially literate adults, and we designed Pigzbe to achieve just that,” Primo Toys, the maker of the Pigzbe wallet, writes in its Kickstarter campaign. The product has already exceeded its $50,000 fundraising goal, with more than 550 backers on board.

Backers who pledge $79 or more before the campaign ends on January 25, 2019 will receive the Pigzbe wallet at a 40 percent discount.
